Title: Detection of epigenetic abnormalities and diagnostic method based thereon
Inventor: PETRONIS ARTURAS
IPC: C12Q1/68
Filed: 2003-06-06
Abstract: The present invention provides a method of detecting an epigenetic abnormali ty associated with a disease. The method comprises identifying, within a eukaryotic genome, a locus having a hypomethylated sequence specific for the disease and an endogenous multi-copy DNA element. The method can also compri se separate steps of identifying a disease-specific hypomethylated sequence and identifying an endogenous multi-copy DNA element, where the steps may be performed in any order, so long as a locus is identified that has both a disease-specific hypomethylated sequence and an endogenous multi-copy DNA element. The disease-specific hypomethylated sequences detected in accordanc e with the present invention indicate putative regions of epigenetic dys- regulation and indicate aberrantly regulated nucleic acid sequences that may cause or predispose a patient to disease, such as, but not limited to, Huntingdon s disease, cancers, diabetes, schizophrenia, or bipolar disorder.

Inventor: TRAN CHINH
IPC: H03F3/58
Filed: 2003-08-26
Abstract: Systems and methods are presented for measuring power levels of primary and interfering signals as well as noise, particularly for satellite transmitted signals. A typical method comprises the steps of receiving a signal comprising a primary signal, an interference signal and noise, demodulating the primary signal to remove a carrier frequency, decoding the primary signal to obtain symbols, estimating a power level of the primary signal based upon the demodulated and decoded primary signal. Additionally, an ideal primary signal can be generated from the carrier power and frequency and the symbols and subtracted from the received signal to produce the noise and interference signal. The noise and interference power is then estimated from the noise and interference signal.
